Koseki or Family Registration @%

 In Japan, the 戸籍 (Koseki) or “family registration system” is mandatory to all households. It requires that the family records all changes in family composition and identity, such as births, deaths, marriages, divorces, acknowledgements of paternity, adoptions, and disrupted adoptions.

It’s required to register one person as the head of a household, and the rest of the members in a household must have the same surname as that of the head. Once a couple gets married, spouses are obligated to have the same surname, and registration of different surnames is not allowed.

Due to the traditional system and the importance of kinship as custom, marriage isn’t only a matter of the bride and groom, but also of their extended family. It’s expected that extended families from both sides are going to have a “family relationship” once a couple gets married in Japan. As such, relationships with one’s in-laws become important.
